Unreal Engine 4 is available for Win10 UWP app dev now

[Jerry.Richards]

Trying to read the leaderboard now using the Stats Manager. Since ReadLeaderboardsAroundUser wasn't implemented I decided to replace its function body:

bool FOnlineLeaderboardsLive::ReadLeaderboardsAroundUser(TSharedRef<const FUniqueNetId> Player, uint32 Range, FOnlineLeaderboardReadRef& ReadObject)
{
	//UE_LOG_ONLINE(Warning, TEXT("FOnlineLeaderboardsLive::ReadLeaderboardsAroundUser is currently not supported."));
    if (!LiveSubsystem)
        return false;

    const FOnlineIdentityLivePtr Identity = LiveSubsystem->GetIdentityLive();
    if (!Identity.IsValid())
        return false;

    const FUniqueNetIdLive UserLive(Player.Get());
    Windows::Xbox::System::User^ XBoxUser = Identity->GetUserForUniqueNetId(UserLive);
    if (!XBoxUser)
        return false;

    Microsoft::Xbox::Services::XboxLiveContext^ LiveContext = LiveSubsystem->GetLiveContext(XBoxUser);
    if (LiveContext == nullptr)
        return false;

    Microsoft::Xbox::Services::Statistics::Manager::StatisticManager^ mgr = Microsoft::Xbox::Services::Statistics::Manager::StatisticManager::SingletonInstance;
    if (mgr != nullptr)
    {
        FOnlineLeaderboardRead olr = ReadObject.Get();
        TArray<FColumnMetaData> cols = olr.ColumnMetadata;
        for (FColumnMetaData data : olr.ColumnMetadata)
        {
            mgr->GetLeaderboard(LiveContext->User, data.ColumnName, );
        }

        return true;
    }

    return false;
}

Unfortunately I need a third parameter for the mgr->GetLeaderboard(LiveContext->User, data.ColumnName, ); call.

That would go to the regular log file. For UWP without a cook server this is %localappdata%\Packages\{Package_Family_Name}\LocalState\{Project_Name}\Saved\Logs\{Project_Name}.log. You should also see it in the Project Launcher output window if running using the Project Launcher, or in the debugger output window if running under the debugger.

Sounds, though, as if an error is not the problem. I suspect the stat is not actually getting the 'Feature on players' profile' flag, and it sounds as though there may be no way to apply that in the current UI for Creators Program titles. Have you had a chance to try retrieving the stat in your own code yet, (e.g. via StatisticManager::GetLeaderboard)?

[MENTION=494622]jsyarrow[/MENTION] - where can I find the log written to in the below code:

    Microsoft::Xbox::Services::Statistics::Manager::StatisticManager^ mgr = Microsoft::Xbox::Services::Statistics::Manager::StatisticManager::SingletonInstance;
    if (mgr != nullptr)
    {
        auto EventList = mgr->DoWork();
        for (auto Event : EventList)
        {
            if (Event->ErrorCode != 0)
            {
                UE_LOG_ONLINE(Warning, TEXT("DoWork error: %s"), Event->ErrorMessage->Data());
                :
            }
        }
    }

I placed a breakpoint in the ErrorCode block but it was never hit. Most likely an error never occurred.

[jsyarrow]

It will be something like:

auto EventList = Manager->DoWork();
for (auto Event : EventList)
{
	if (Event->ErrorCode != 0)
	{
		// Event->ErrorMessage should have more details
	}
}

- Make sure you've checked the box to 'Feature on players' profiles'

I think the 'Feature on players' profiles' is what concerns me the most. It isn't shown on my 'New featured stat/leaderboard' dialog:



I've seen this mentioned and other peculiarities in the documentation yet it isn't visible on mine. I was hoping that a Dev Center Portal update was coming.

- If you're not already, you should capture and process the returned events from the DoWork call on the StatisticsManager. These might provide some clue if there's an error encountered.
- Try retrieving the leaderboards in your own code - this will be the only way to display global leaderboards in any case, since the dash/Xbox App focuses on social.

How do I attach to the DoWork events call stack? I'll look for it but if you happen to know that may save me a bit of time.

[jsyarrow]

A few ideas on the stats update:
- Make sure you've checked the box to 'Feature on players' profiles'
- If you're not already, you should capture and process the returned events from the DoWork call on the StatisticsManager. These might provide some clue if there's an error encountered.
- Try retrieving the leaderboards in your own code - this will be the only way to display global leaderboards in any case, since the dash/Xbox App focuses on social.

You beat me to it on deployment to Xbox. There are indeed some limitations on package size at the moment, and using a network share or deploying loose files are the best options for working around them.

[Jerry.Richards]

[MENTION=494622]jsyarrow[/MENTION] - A smaller application size worked. I was able to build and deploy the UWP Third Person sample onto my Xbox:




And running on the Xbox:




This confirms (mostly) that my steps are correct, and my setup is working.

The test game size is: 85.4 MB
The actual game size is: 3.53 GB

When I try to deploy my game the Xbox Device Portal timesout. Is there something I can do?

[EDIT]
With Windows Explorer I can copy my AppX file but I don't know where it should be copied to and how to install it (yet):




[EDIT]
Using Register a game from a shared network location on the Xbox One Dev Mode console I am able to install my game, which is 3.53GB in size.

For those that may not know, this is a two step process:

1. Share the folder:
a. From Windows Explorer right-click the folder name and select Share with and Specific people...



2. Enter the needed location and credentials on the Xbox One:
a. Select Register a game from a shared network location
b. At the Add a network share screen enter the location to the AppX manifest, for example, \\COMPUTERNAME\Releases\2017.07.08.UWP\LongshotHero
c. At the Username enter: COMPUTERNAME\username, and password

[MENTION=494622]jsyarrow[/MENTION] - I'm hoping not to get too far ahead as there a couple of other issues that I noted.

Now I'm trying to test on the Xbox One but unfortunately the Xbox Device Portal deployment fails. Is there an FTP option available?

[Jerry.Richards]

[MENTION=494622]jsyarrow[/MENTION] - As mentioned above, I added FTickableGameObject to the FOnlineLeaderboardsLive class, along with a couple of other support functions:

class FOnlineLeaderboardsLive : public IOnlineLeaderboards, public FTickableGameObject
{
public:

    virtual void Tick(float DeltaTime) override;
    virtual bool IsTickable(void) const override;
    virtual TStatId GetStatId(void) const override;
}


bool FOnlineLeaderboardsLive::IsTickable(void) const
{
    return true;
}


TStatId FOnlineLeaderboardsLive::GetStatId(void) const
{
    static TStatId statId;
    return statId;
}


void FOnlineLeaderboardsLive::Tick(float DeltaTime)
{
    Microsoft::Xbox::Services::Statistics::Manager::StatisticManager^ mgr = Microsoft::Xbox::Services::Statistics::Manager::StatisticManager::SingletonInstance;
    if (mgr != nullptr)
        mgr->DoWork();
}

The class does tick and DoWork is called with each tick (maybe not with some exclusions, such as it's not ready).

With that should I be able to see my Leaderboard updates (assuming I did it correctly)?


[EDIT]
According to the content on this page:

https://developer.microsoft.com/en-u...ve-experiences

the stats should be visible on the Xbox One dashboard, and on the Xbox app on Windows 10. Unfortunately I don't see it. I've been re-reading several pages with no luck seeing the stat:

https://developer.microsoft.com/en-u.../data-platform
https://developer.microsoft.com/en-u...7/player-stats
https://developer.microsoft.com/en-u...stats-updating

Is there a difference between the C# (https://github.com/Microsoft/xbox-live-api-csharp) and C++ (https://github.com/Microsoft/xbox-live-samples) API's?

This may be a dumb question. . .but could I be inadvertently using the wrong libs/dlls? I would think that the underlying call to the service would be the same though regardless of which was used.

[MENTION=494622]jsyarrow[/MENTION] - I don't think the update to the leaderboard/achievements is working. I read the documentation and my settings look right but I don't see any indication on the Xbox for Windows 10 Achievements. Are you able to investigate this on your side?

[Jerry.Richards]

I haven't had a chance to play with the new StatisticsManager API yet, but from a quick look at the header I'd guess you're missing a call to AddLocalUser.

Adding the call to AddLocalUser did fix the problem. I might not be performing it at the most optimal location but it did stop the exception from occurring.

Also make sure that you're regularly calling the DoWork method, probably from a Tick method on FOnlineLeaderboardsLive.

FOnlineLeaderboardsLive doesn't inherit from a tickable component, which we might have to include if calling DoWork is needed.


Btw, where would I see the posting? I don't see anything in the Xbox Live portal on my Windows machine nor anywhere on the Dev Portal.

The SocialManager-based implementation of FOnlineFriendsLive might be a decent example of how to deal with these manager objects.

[Jerry.Richards]

StatisticManager::SetStatisticIntegerData throws a "User not found in local map" exception:



The code is fairly straightforward:

bool FOnlineLeaderboardsLive::WriteLeaderboards(const FName& SessionName, const FUniqueNetId& PlayerId, FOnlineLeaderboardWrite& WriteObject)
{
	UNREFERENCED_PARAMETER(SessionName);

    if (!LiveSubsystem)
        return false;

    const FOnlineIdentityLivePtr Identity = LiveSubsystem->GetIdentityLive();
    if (!Identity.IsValid())
        return false;

    const FUniqueNetIdLive UserLive(PlayerId);
    Windows::Xbox::System::User^ XBoxUser = Identity->GetUserForUniqueNetId(UserLive);

    Microsoft::Xbox::Services::XboxLiveContext^ LiveContext = LiveSubsystem->GetLiveContext(XBoxUser);
    if (LiveContext == nullptr)
        return false;

    Microsoft::Xbox::Services::Statistics::Manager::StatisticManager^ mgr = Microsoft::Xbox::Services::Statistics::Manager::StatisticManager::SingletonInstance;
    if (mgr != nullptr)
    {
        for (FStatPropertyArray::TConstIterator item(WriteObject.Properties); item; ++item)
        {
            Platform::String^ itemName = ref new Platform::String(*item->Key.GetPlainNameString());

            int32 itemValue;
            item->Value.GetValue(itemValue);

            long long llValue;
            llValue = itemValue;

            mgr->SetStatisticIntegerData(LiveContext->User, itemName, llValue);
        }

        mgr->RequestFlushToService(LiveContext->User);

        return true;
    }

	return false;
}

Am I using the call to GetLiveContext with the user correctly?
I've also tried using LiveSubsystem->GetDefaultLiveContext() but that didn't work either.

Any help is appreciated.

I cannot access the stats namespace:

You do indeed want the types in Microsoft::Xbox::Services::Statistics::Manager. Looks like the name change is part of the WinRT projection. Sorry for the confusion.

[Sparkash]

Great, that update fixed all my pathing issues. Thanks!

[Jerry.Richards]

[MENTION=494622]jsyarrow[/MENTION] - I'm happy to report that the change worked and I am now able to Debug UWP64 projects. Thank you for the help.

Now. . . what is the best way to make use of the Stats Manager API that you mentioned above?

I cannot access the stats namespace:

using namespace Microsoft::Xbox::Services::Stats::Manager;

Does this go back to the EraAdapter problem?

I can access other namespaces:

using namespace Microsoft::Xbox::Services;
using namespace Microsoft::Xbox::Services::Achievements;
using namespace Microsoft::Xbox::Services::Leaderboard;
using namespace Microsoft::Xbox::Services::Statistics;
using namespace Microsoft::Xbox::Services::Statistics::Manager;

I do see a change for the renaming:
